Steady State Calculations of Model IEEE Networks
Kintr, Kryštof ; Vyčítal, Václav (referee) ; Krčál, Vít (advisor)
This bachelor thesis is focused on power-flow calculation. At first the problem is initially discussed in general. This is followed by a brief description of the mathematical methods used in the calculation, followed by an overview of the software that enables this calculation. Then, the modelling of some basic power system elements is described and selected IEEE test feeders are described in more detail. Thesis continues by a description of the OpenDSS computational program and its capabilities, including a description of the features of the related OpenDSS-G program. The principles of code writing are presented using examples from a selected test feeeders IEEE 13 and IEEE 30. It is followed by a description of automated computation, for which a script was written in MATLAB and a unified data entry format was suggested in EXCEL, which is the main contribution of the thesis. Finally, the results obtained by the automated computation of selected test feeders from OpenDSS are compared with the results from the demo codes for OpenDSS as well as from other computational programs, pandapower and GridLAB-D.
